City officials were confident the waste water treatment plant (that serves around a dozen other neighboring communities) will make it through the night, thanks in part to a massive sandbag wall lining the perimeter.

Over the weekend the city moved around $3 million dollars in equipment that’s not needed for the emergency to drier locations, just in case.

The flooding means the plant is processing more than triple the usual amount of water. Over the last three days, the city says the plant has treated 150 million gallons of water a day, compared to an average of 42 million gallons a day.

People are still being asked to conserve water; take shorter showers, hold off on washing laundry and dishes.

“We expect to be safe through the night,” the city’s Environmental Services Manager Mike Lunn said in a written statement.

“The combined performance of our flood walls, our pumps, professional staff, and volunteers has been truly amazing. We must, however, continue to be diligent in monitoring the situation,” Lunn said.

The city is no longer calling on people to help fill and move sandbags, for now.

“I can’t possibly imagine what else we could do to react to this situation,” Mayor George Heartwell said, “We realize that things could change dramatically in the next few days with more rain or if issues associated with structures – such as buildings, walls, or bridges - arise.”

The crest will head to Grandville soon, where the city library is now taking on some water in the basement.

In Lowell, upstream from Grand Rapids, the water is already beginning to recede. There’s been very limited access into the city, with a number of bridges closed. But the barricades are predicted to move off Main Street before the Monday morning commute.

Sunday 4:30 p.m.

Electricity is being rerouted in Grand Rapids because of the flooded Grand River.

Officials from Consumers Energy said Sunday there are four high voltage distribution lines that run just under the Fulton Street bridge.

On Sunday the Fulton Street bridge was closed. The water is high enough there’s concern big trees floating down the river could snag high voltage electrical lines just under the bridge

The water is high enough there's a concern that big trees or other debris floating down the river could snag the lines and cause safety concerns so they’ve de-energeized the lines. Electrical services have not been impacted because of the move.

Once the river recedes they’ll reopen the bridge. But officials couldn’t estimate how long that will be.

The Grand River is expected to crest Monday around 2 a.m. at 22.3 feet.

At a press conference Sunday afternoon Mayor George Heartwell thanked the hundreds of volunteers who’ve been filling and stockpiling 6,000 sandbags an hour over the weekend. He called for more volunteers this afternoon and evening.

“Even though we’re the most incredible volunteering city in the world, we need more,” Heartwell said, “Please help us protect our city.”

City-owned buildings have already been lined with the bags. So the 50,000 that remain are primarily for residents and business owners who need then, “or the possibility that the skies open up again this week, we get a ton of rain and we get a resurgence of these levels.”

Rain is in the forecast as early as Tuesday.

Michigan’s second largest city remains under a state of emergency because of significant property damage to a number of buildings in the downtown area.

It’s estimated that around a thousand residents in mid and west Michigan have been evacuated from their homes. Some have already been able to return.

Sunday 11:10 a.m.

Here's the updated Grand River forecast from the National Weather Service. The predicted crest in Grand Rapids has come down again. It's now expected to crest at 22.3 feet at 2 a.m. Monday morning. At the moment, the river is about half a foot from its expected peak.

Sunday 10:15 a.m.

The Grand River is at an official new record in the City of Lowell. Police there are urging only resident, business owners and emergency personnel to enter the city. Gawkers had flocked there yesterday to see the damage.

In Grand Rapids, MLive.com is reporting Mayor George Heartwelll has ordered the Fulton Street closed “ASAP.” He’s concerned about debris in the river snagging a major utility cable.

Heartwell said the Consumer’s Energy cable in question runs lengthwise under the bridge and “powers all of downtown.” It runs alongside other city power and fiber-optic that are strapped to the underside of the bridge.

Workers were on the bridge to pluck bobbing logs and other debris that could get under the bridge and snag the cable.

It could take up to 6 hours to full-de-energize the cable, Heartwell said.

It’s not immediately clear what the wider effects of the cable’s de-energization are.

“This is not a breach in the flood wall, this is water coming up from the hydrological pressure that’s exerted coming up out of the ground and flooding their basement, I believe to a level of five feet or more,” Heartwell said. Electricity was cut off from the building for safety.

“The flood walls are holding … and we expect that the floods will be contained fully within those walls” Heartwell said.

The National Weather Service is now predicting the river will crest at 22.7 feet early next week. It’s the second time the crest prediction has been lowered. As of Saturday afternoon the level was around 21 feet.

Lots of people with strollers and pets were seen taking pictures of the flooding.

“Although there’s a temptation to get out and view this flood, view it from a distance please. Those waters are high and they’re fast and they’re unpredictable,” Heartwell warned.

City Manager Greg Sundstrom says city staff has been able to handle the flooding situation so far.

“I don’t think it’s really deterred our resources at this point, but we have great concern that we do not have extra resources to fish somebody out of the river right now,” Sundstrom said.

Heartwell said the emergency declaration probably doesn’t mean much for residents. It has more to do with potential state and/or federal funding if a “disaster” is declared in the future.

He’s asking residents to still conserve water when possible. He’s also asking for volunteers to help fill and disperse sand bags on Sunday.

Michigan State Police helicopters have done fly-overs in the region to help assess the flooding damage.

Saturday 2:00 p.m.

Grand Rapids Mayor George Heartwell has issued a state of emergency until the waters recede.

“City of Grand Rapids officials are greatly concerned that significant property damage, injury and losses may be sustained through flooding on public and private property and within local streets and rights-of-way.”

Saturday 10:30 a.m.

Floodwaters are causing problems in downtown Grand Rapids. Smoke was reported outside of the Courtyard Marriott. This tweet is from Aaron Aupperlee of the Grand Rapids Press:

Aupperlee tweets the smoke has now subsided and was from a generator. Pumping equipment was sent to the Marriott.

Aupperlee reports people were evacuated from the Courtyard Marriott. Garret Ellison of the Grand Rapids Press reports people are being evacuated from the Plaza Towers Apartments in downtown Grand Rapids.

Business owners in downtown Lowell are stuffing sandbags and bringing items up from their basements as flooding is expected over the weekend. Representatives of a “vast majority” of the 30 Main Street businesses in downtown Lowell met with city leaders and police on Friday, April 19, to discuss the expected flooding.

"Local state of emergencies" have been declared in Lowell, Midland, and Kent County.

The predicted crest for the Grand River in Grand Rapids has declined for a second time.

It is now expected to crest at 22.7 feet early Monday morning. Which would still break the high water record in that city. Here's the latest prediction from the National Weather Service:

Friday, 5:02 p.m.

A "local state of emergency" was signed in Kent County today. It's the first step in receiving federal help should people need it.

Kent County is experiencing the worst flooding in more than a century. The flooding crest is still perhaps two days out, and hydrologists are saying the water will not recede below flood stage until the middle of next week. Kent County Board Chairman Dan Koorndyk signed a Declaration for a Local State of Emergency today. This will allow us to receive damage assessment resources from the state, and is the first step for possible Federal Emergency Assistance.

Michigan Public Radio Network's Rick Pluta reports the state is now getting involved too.

The state's emergency operations center has been activated in response to weather-related emergencies in several Michigan counties. Midland, Osceola, Ottawa and Newaygo counties have all declared a local state of emergency due to storms and severe flooding. The emergency operations center tracks events and helps coordinate responses.

Friday, 3:54 p.m.

Here's a video of water being pumped out of the Amway Grand Plaza Hotel. Sand bags are being used to try to keep rising floodwaters out.

And this video shows the rising waters near the Gerald Ford Museum:

Friday, 2:04 p.m.

Smaller rivers and creeks in West and mid-Michigan are expected to recede today, but mainstem rivers, such as the Muskegon and the Grand, will continue to rise until they hit their peak later this weekend or early next week.

MLive's Aaron Aupperlee put together this map of road closings in West Michigan.

When you come upon a covered roadway, authorities warn "turn around, don't drown!"

Rainfall totals from Wednesday afternoon through Thursday night ranged from 1 to 3 inches in most areas. A heavier swath of rain fell from the Lake Michigan shore at Holland and Grand Haven east in the Grand Rapids area. In this area, (Ottawa, Allegan and Kent Counties) some 4 to 5 inch rainfall totals were found. Flooding will continue on larger rivers like the Grand and Muskegon into next week with crests occurring late in the weekend. Smaller creeks and streams will begin to recede today as widespread rainfall has ended and only scattered showers are expected today. Flooding of low lying areas and farmland will likely continue today and slowly recede over the weekend. If you live along a stream or river closely monitor levels today and into the weekend. Be prepared to move to higher ground.

Grand Rapids city officials are feeling a “sense of relief” now that the Grand River is receding.

But Mayor George Heartwell hesitated to declare victory over the worst flood on record, just yet.

“We will continue to be vigilant even though the worst is behind us,” Heartwell said.

There’s rain in forecast for Tuesday, so conditions could change. But the National Weather Service predicts the river will go down as much as a foot per day until it gets back to normal levels on Thursday.

That’s good news for riverfront hotels and businesses which are still pumping water out of their basements and parking garages.

City Manager Greg Sundstrom says the city has spent between $300,000 and $500,000 so far in overtime pay and equipment. But Heartwell says it's paid off.

“Because we were proactive we were able to weather this storm,” Heartwell said. After several days in a row of press conferences to update the media about the flooding, Heartwell hopes Monday’s conference will be the last for a while.

“There’s a sense of relief,” Heartwell said, “I am so incredibly proud of this community and the way it responded to this threat.”

Businesses and residents in communities along the Grand River, from Ionia to Grand Haven, are still drying out basements and assessing the damage.

On Monday crews carefully moved large debris stuck to the side of the Fulton Street bridge. They guide it underneath the bridge and four high voltage transmission lines.

Consumers Energy spokesman Roger Morgenstern watched a small crane pull a 20-foot-tall dead tree out of the water.

“It’s huge! And then I don’t know how they’re going to – I’m not an engineer but you get to a point that thing is going to be too heavy for that crane to pick up,” Morgenstern said, “It’s amazing what mother nature is sending down the river for us.”

Update 3:33 p.m.

Michigan Radio’s Dustin Dwyer traveled to Lowell, Michigan today to get a first-hand look at the damage there. WOOD-TV reports Lowell was “among the hardest hit West Michigan cities.”

The Grand River peaked at 19.02 feet yesterday at 8:45 a.m. It was just a hair over its previous record of 19.00 feet set back in 1948.

Dwyer spoke with Matthew Silverman of Lowell who owns around 20 acres of land in the area – most of it was underwater.

Silverman said water was flowing into his basement and he lost his boiler and water heater.

“A couple of the houses down the street, they got inundated... A couple of the people didn't even have flood insurance, so they're going to be hurt pretty bad,” said Silverman.

“Nobody was shocked. Everybody was prepared. Everybody was working really hard.... We had a constant flow of people just coming up, 'Do you need help with anything, what do you need?'” he said.

Silverman said the town became a gathering place for onlookers trying to experience the high waters.

“People were launching boats out of my flower bed the other day, with no regard for any private property. They were paddling right over the top of my fence - hitting my fence,” he said.

Silverman said the steady stream of kayakers and the thousands of onlookers on foot and in cars has been a little stressful.

“I mean, it's hard when you're working 24 hours a day, trying to keep your house above water, trying to help your neighbors out and you got people walking through your yard without permission, taking pictures of your house, walking into your backyard,” Silverman said.

12:45 p.m.

The Courtyard Marriott and Plaza Towers Condominiums in downtown Grand Rapids were evacuated this past Saturday morning. The hotel is expected to be shutdown until Wednesday, no word yet on when Plaza Towers residents can return.

The weight of the water from the swollen river found a way to push upward and break the slab floor in the N corner of the hotel basement parking area. Above that area is the retail parking lot. Our structure is not believed to be damaged or impacted in any way.

The water poured into the basement which led to an immediate shutdown of electricity and the evacuation.

Michigan Radio's Lindsey Smith reports hotels and office buildings in downtown Grand Rapids along the Grand River are still pumping water out of their basements. She says the river is "expected to hit record levels downstream today in cities like Grandville, while upstream in Lowell and Ionia people are assessing the damage."

11:05 a.m.

Small creeks and streams around West and mid-Michigan hit their crests late last week. As they emptied out, they filled the mainstem rivers.

A spokeswoman for the U.S. Army Corps of Engineers says crews are stationed along the 13-mile physical and electronic barrier along the Des Plaines River, which is experiencing record flooding. Felicia Kirksey no carp have been spotted so far, and that the Corps is confident electronic pulses will continue to deter the invasive fish. More rain is expected in that region tonight, but will taper off tomorrow.

She'll have more for us in a separate post.
